The acceleration of a different speck of dust is 40 m/s.

Since the radius is been given as double and angular velocity will be constant, we can calculate the centripetal acceleration as

a = (2r)ω²

If we substitute the given values of r= 2r , and ω²= 20m/s.

Then we have

[tex]a= (2*20) = 40 m/s^2[/tex]

Therefore, acceleration of a different speck of dust is 40 m/s.
